I finished my roller BBC motor in my T-Bucket, and now installing a brand new set of Sanderson side pipes, I find the flange hits the bottom row of head bolts. They're very generous around the exhaust ports, my old pipes were shaped close around the port O.D., which allowed them to clear the bolts.

They're ceramic coated, and I know grinding the flange will void the 5 year warranty, I'll call them in the morning., I hate the thought of grinding ceramic coating off these $900.00 headers. The worst part is they're only returnable for 30 days, I bought these in January while collecting parts.,

I'm just curious if any of you all have used Sanderson pipes and had any issues like this.

Sanderson makes nice headers but the inside of the ports are "GAWD AWFUL", there's enough welding slag in there to build another set of tubes.......anyway when you call ask for Jay, he one of the designers and builders.

I called this morning before logging in here and talked to Donna. She acknowledged they won't clear ARP bolts and said send them back we'll relieve and re-coat them, freight at my expense, to the tune of over $100.00. My other option is to grind them myself and coat with VHT on the edge of the flange, which I will probably do.

They are very nice pieces, I don't see a lot of slag like mentioned above, but feel they need to address that issue on their order form.

Thanks for the reply.

After gritting my teeth over grinding the new exhaust, I ground the heads of the four (per side) offending bolts a small amount, taking them down to the height of stock head bolts, a little block paint and good to go.

Ah yes! Sanderson headers and ARP bolts - or any others for that matter. I ended up with some Percy's split locking bolts which have proven to work well.

While the slag and trash may not be visible in a set of 'bucket headers, I can assure you that every conventional set I've seen has had lots where the 4 tubes meet at the collector. I bought my Sanderson's uncoated, spent hours with a die grinder and long burrs cleaning MIG ends, slag, partially closed off tubes. I then sent them off to Jet Hot which I consider the best ceramic coating

The Sanderson headers I bought for my 5.0 HO '27 RPU T roadster had a leak at one of the the tube to head flange joints. I bought them raw, then had them coated, then found the leak. They paid for shipping back to them, they weld repaired their defect and sent them back to me.
